Titan Souls is an action-adventure boss rush game. It takes one hit to die but also usually one hit to kill a boss. You have one arrow and when you misfire you need to go regather it to try again. Boss fights are varied and interesting. The game should be great but as the game went on fights got harder a particular issue stood out more and more.

Have you ever replayed a game you are familiar with, but instead of just going through normally you imposed some restriction? I look at self imposed restrictions in games and how to design a game to allow it.
